    Hi all. im putting a system in my workshop offices with 5 rads and an oil boiler. ive planned it for open vent heat only condensing oil boiler as i already have it however ive just been offered a much newer combi that id like. ive never needed to know this so never asked before but can i use the combi for heat only? i dont see why not as no water demand will ever be asked for, but id like to confirm?

    thanks all

    hi
    most likely be a pressurized system, just need a filling loop.
    the boiler output, will be for hot water, so heating load will be less.
    basically no problems

    Getting the boiler output correctly sized to the radiator requirement is fairly important,using a combination oil boiler will need some installer adjustment and a means to stop pre heating of the internal heatstore.

    All doable :)

    many thanks for the reply guys. another plumber has said simply stick a tap on the wall connected for the hot water and open t once a week to keep things good. think i might do that,
